I zen'of the United States, residing at'Salt Lake -City, in the countyof Salt'Lake and State of Utah, have invented new and useful Improve-'m'entsin Sand and Slime Separators, of which the following isaspecification.

,- My invention relates 'to certain new and 'use ful improvements inseparating-machines designed, essentially, for working materialscontaining precious metals and wherein the separation ofjthe sand andslime is effectedautomatically; and my invention consists of the partsand the constructions-and combinations ofparts, which Iwill-hereinafterdescribe and clai An. essentialcharacteristic of my present invention isthe-provision of ia wheel or revoluble member-having pockets orcompartments into i which agitated pulp is delivered through a pipe orlaunder, sai' wheel being periodically rotated, whereby when aconipartment of the bucket is filled theoverflow will automatically tripareleasing mechanism and allow the wheel to turna distance sufficient tobring a succeeding empty compartment beneath the supply and to allow thea material in suspension inthe preceding compartment to be poured off,the heaviermaterial remai ng at the bottom'of the comparts.

' 1"I illustrate one form of. such frame and which frame is providedwith vertical standards, in the upper portions of which a hori zontalshaft 10 is appropriately mounted. Upon thisshaft'is mountedor'supported the separating-wheel B, comprising end disks 11 andradially-arrangedpartitions 12, which "I divide'the wheel into a seriesof separate comthe material to be separated.

Accordingly 1 pre er. toform the launder with an iar'm extension 19,'in which is fixed a shaftor rod 20, which is journal'ed in a suitable bear ing in'astandard 21,rising from themain frame.

provided with a shiftable weight or counterpoisej 23, which is intendedto' be overbal anced by the weight of the overflow'in the box or vessel18 and is also designed to return The rod or shaft is rigichwith an arm22, whicheXtends horizontally at'right an-v gles to the rod or shaft,-said arm 22-b'eing the launder and its adjuncts to normal position whenthe'volume of overflow in thebox or vessel is reduced and the combinedweight of this box or vessel and the launder falls below the weight ofthe counterpoise on the le- In other words, the launder is,

in efiect, mounted upon substantially a counterbalancedlever whosefulcrum isthe shaft or rod. p

The swinging launder is connected above its axis withione' end of a rod24, whose opposite end is connected with a pivoted plate 25,

located in the launder 14 and by which when l I the launder 16 begins toswing outward the flow of the pulp from the launder is diverted from thecompartment of. the wheel just filled into the succeeding compartment.

"Projecting from one of the end disks the compartmentewneel are a numberof pins 26, I

1 'der, 1'4, in which position the parts are nornmally held and untilthe overflow from this from falling upon the partition next below it,

one for each compartment and located relative thereto, so that one ofthese pins will contact with the bent end'27 of the shaft or rod 22, andthus stop the revoluble movement of the, wheel at such a point that theuppermost empty com artmentwill be in line with the discharge 0 pulpfrom the launcompartment overcomes the counterweighted launder and itsadjuncts and moves the shaft or rod to permit the engaged pin to escapepast the bent end of the shaft, and thus allow the wheel to make itspartial revolution. Another series of pins 28 is provided, alsoprojecting from the end disks of the wheel, and these pins are designedto successively engage exterior bent arms 29, which form a part of asuitable inclined apron 30, so placed that it normally entersthecompart' ment of the wheel next below the compartment being filled,whereby theoverfiow from said last-named compartment isprevented but isdirected u on the apron and by the latter is in turn irected into anappropriate trough or launder 31, arranged below it. The apron ispivotally mounted at 32 in the base of the main frame and has a leverarm32.

upon which. a weight is adiustably mounted, thereby ccenterweighting theapron and automatically returning it to normal position after it hasbeen pushed forward by the par tial rotation of the wheel and thepushing ac-. tion of the pins 28, before mentioned.

1n connection with the trough or launder 31 I prefer to employ asplasb-plate'32, Fig. "3, for receiving the splash from the apron andconducting the slime to the trough 31.

In a separator of the character described it will be found useful toprovide means for governing the movement of the wheel, and while variousforms of governors may be used in connection with the wheel and otherparts heretofore described and two forms of g ov ernors are shown in thedrawings I prefer to use a governor of the general type of a dash pot.Accordingly in Fig. l I illustrate a governor which comprises anexterior cylinder or vessel 33, adapted to contain Water or other fluid.Within this cylinder and oper" ating somewhat on the order of a pistonis a hollow cylinder or vessel 3 closed at the top and having arelatively small opening in its bottom, said inner cylinder or vesselhaving an opening in its closed top controlled by an outwardly-openingvalve 35. An air-cock 36 is also fixed in the top of the inner cylinderor vessel and controls the rate of movement of said vessel. w i

The inner vessel 34is connected-by a rod or link 37 with one end of alever 38, fulcrume'd "any other desire at or about its center to astandard 39, rising from the base-frame, and the opposite end of i thelever is likewise attached to a second governing device comprising innerand outer cylinders 33 34 and connect-ions similar to those beforedescribed. These two sets of cylinders form an alternately actinggovernor, and when the inner cylinder of one is elevated thecorresponding cylinder of the other is lowered, as I will presentlydescribe. To communicate the partial rotation or the wheel to thegovernor mechanism, I. show fixed upon the axis of the wheel a largegear- Wheel 40, and in a standard 41 I journal above the gear-wheel 410a pinion 42 of such size relative to its engaging gear-wheel that aone-half revolution is effected while the separator-wheel B c ves fromone position to osition or in the eightcompartment whee (represented inFig. 3) while the separator-wheel makes a oneeighth revolution. If thiswheel consists of more or fewer compartments than shown, the gearing isarranged accordinglv T he shaft of the pinion or smaller gear-wheel 42is provided with a crank 43, which connects, through the medium of therod or link 44,

with the centrally-fulcrumed lever, whereby as the separator begins itsmovement to unloadafilled compartment and bringan empty compartment inposition beneath the sand and slime supply the described governorconnections result in rocking the lever 38 to ele- Vflf E the then lowerand filled inner cylinder of one girverning device and at the same timelower the like cylinder of the other and com anipn governor. When thefilled cylinder is thus being raised, the contained water or fluid willpass out of it through the bottom opening and into the outer cylinderand air will enter the inner cylinder through the valve 36, and when theinner cylinder of the other governor is being lowered the water or fluidin the outer cylinder witlrgvhich it connected will be is laced and willenter said inner vessel an relieve any sudden shock or movementwhichmight be given the compartment-wheel. The amount of aircushion and thecorise uent speed at which the inner cylinder may lower is controlled bythe air-cock 36' before mentioned. 1

In Fig. 4 1 illustrate a modified form of governor employing thealternately-acting cylinders before mentioned; but in this case theactuating devices are somewhatmodified. For instance, instead of thetoothed gears of Fig. 1 I show insaidTig. 4 groups of pins 4., locatedrelativejroeach com artment of the separator-wheelhnd adapts to engagepins or teeth 46 on the enlarged head 47 of a fulcrumed lever 48, therebeing in practice two levers and two groups of pins and two pairs ofgovernor-cyliuders and the parts being so arranged in practice atopposite ends of the separator-wheel tnat one set is operating whenother set is idle.
